What software you used for this circuit designing ?Originally posted by abhijeet080808 View Post

@ abhijeet, bro do you still have the pics that you uploaded on page 1? there's not visible anymore and I really want to see how you've wired the leds

Just do 1 thing - use newer UG2 Pulsar's clear lens. It looks loads better.Originally posted by Ramborider View Posthere is mine pulsar leds back light,sorry for quality of pic taken by mobile cam

It will be the same! Lets see some pics of the LEDs on the bike...Originally posted by Ramborider View PostI have converted to Leds on rear light
used that 220ohm and 5 led on each.
Thankyou very much abhijit,im very happy with its brightness.
what is normal life of led usd in our tail lamp?...normal life span is about 10000hours but dont have idea about use in retrofit in our bike.
Well.. u are free to try it and let us know!Originally posted by Ramborider View Postis there any Led used un headlight unit??
when i saw brighness of everedy 3w led torche i was shoked!!white light and piercing beam that can traveld 2.5km!!! its on that box but when i was saw this in night,bloody light focus traveld as higher than 400-500m and even brighter!!!
why dont used such high tech product for automobile!!!which are so much efficient!!! even i was also start thinking that how to fix in my bike
Even I thing they are quite good these days..

Use 200/220 Ohm resistor with 5 LEDs.Originally posted by Ramborider View PostHii abhijit,have buy that middle one but emiting red light so i have to connect 30 led,how much voltage it requred ??i mean have to conect with set of 5 then how much resistance requred?? [ATTACH]39904[/ATTACH]

Nice work bro. I'm an electronics student myself and i want to do something like this in my Pulsar 150 Dtsi. Can you explain how you connected the circuit to the supply?

Originally posted by abhijeet080808 View PostCan you please reply to these queries
1) Is the number of LEDs too much?
Yes, use 4 LEDs per 'line'. Use more such 'lines' to get it total 48 LEDs. Use 300 Ohms per line.
2) How much watts will the above setup take, parking and brake?
Around 1W
3) What is the forward voltage of the above said LED?
Approx 2V
4) Will this setup consume more watts than a stock parking bulb?
No
5) What changes should I make to the above setup?
As answered above.
Thanks a load bro

First of all, I'm novice to electronics
Originally posted by abhijeet080808 View PostYes, LEDs can be and are generally connected serially as shown in the diagram. The number of LEDs you connect serially and the supply voltage determine the value of the resistor used.

I made a LED light for my pulsar 150 UG2 like this
I used 0.5mm transparent LEDs emitting red light
Resistor = 100 ohms
48 LEDS to glow when applied brake
24 LEDs for parking light
Diode and capacitor is the same as you suggested
Setup works ok, but not satisfied with the glow of those 48 LEDs when applied brake.
